Write history, keep a diary
summary
Using Git as a diary lets code history answer “when” and crucially “why”: commit messages store intent so future debugging and feature tracing works. Practical rules: write atomic commits, use a short subject + body and the 50/72 rule, include ticket links and references, prefer git add -p to stage hunks, rewrite local mistakes with git commit --amend or git rebase -i, search history with git log -S and git blame, avoid merge-bubble commits by using git pull --rebase, and skip squashing that erases fine-grained reasoning (analysis used 151 million commits to show common bad messages).
